#530 of 1886 Accelerator Surge by rebecca1880

Oct 05, 2006 (6:31 pm)

Replying to: smurf6 (Oct 03, 2006 8:20 pm)
I recently traded in my 2000 Jeep Wrangler (160,000 miles) for a new 2006 Jeep Wrangler. My new Jeep is a Sport model with an automatic transmission. Over the past 3 months I have experienced what seem to be "power surges" when decelerating. It occurs while I am driving and apply the brake to either slow down or stop. The engine revs and I feel the Jeep lunge forward as if the accelerator has been applied. It only lasts a split second and since I have my foot on the brake pedal, it doesn't lunge forward very much, perhaps a matter of inches if anything. It doesn't happen all the time, in fact it has only happened 3 times since I bought it 3 months ago. I have taken it to the dealer twice already and they can't diagnose the problem and therefore can't fix it. I want to get this resolved as soon as possible because it could cause an accident and the Jeep is still under warranty. Anyone ever experience this who can help me?

Thanks for the heads up. I am not messing with it. I do have A/C and did not even think that would be affected. I knew it could not have been as simple as Haynes made it look. I also believe they start with the heater core and build the car around it.

Yeah it is not shot fortunately, but it is not exactly great. Just wanted to kick the idea around. Wouldn't spend the money now when it drives pretty smooth.

Always nice to hear of someone getting good use from their Jeep. Was it a reliable 160K?

I can only give you straws to clutch at I'm afraid. The first (which you won't like, but do think about it) is that the main cause of this problem is just catching the throttle pedal with the edge of your shoe when you brake. We very often make the minimum of movement with our foot from the 'go' to 'stop' pedal, and it's usually only evident when you look at the wear pattern on the brake pedal.
I know I'm at fault on this.
 
The second reason is much less common and concerns a fault in the brake booster. What happens is that the booster uses, or allows to bleed off, more vacuum than is normal. This has the effect of mimicking an inlet manifold leak, a symptom of which is to increase engine revs. This can be a constant or intermittent fault.
 
Sorry I can't be of more help, but it's especially difficult to diagnose an intermittent problem.
 
Good luck!

Interesting and sad that this is occuring in a new 2006 especially when, if you read back over the last year, numerous Jeep owners have reported lunging problems and all that they went through. The jeeps effected have gone way back to 98's (mine) and the Chrysler defect is still ignored by the manufacturer. Search lunging problems and stalling problems in jeeps and you will hear the cycle of problems. The fact that it's happened 3 times in 3 months is not an ONLY problem. That's way too often, too soon.

I loved that Jeep and was very heartbroken to have to trade it in. I always kept up with the regular maintenance on it and it never had any major problems. The only reason I traded it in was because I drive so much I would have been over 200,000 within the next 6 months and it would only be a matter of time before I would have to start dumping money into keeping it running. I also figured it would be in my best interest to trade it now while it was still in great condition and could get a good amount for it and also get a great deal on the overstock 2006 Jeeps.
Sorry I can't be of more help, but it's especially difficult to diagnose an intermittent problem.
Thanks so much for your thoughts on this problem. (It is funny you should suggest it could be my foot because my brother said the same thing; however, I can tell when I "bump" the pedal and unfortunately that is not the cause of this issue.) I guess only time will tell if it will be on going problem or if it can be fixed. Thanks again.

Thanks for the information. I will definitely do some more research now that I know others have experienced similar issues. I sincerely hope that there is a way to fix this problem though... I spent a lot of money custom ordering this Jeep and expected it to be in perfect condition. I am concerned that it is having this safety issues already. Thanks again!

#537 of 1886 '94 Wrangler Stalls While Driving by mikeylito

Oct 09, 2006 (4:11 pm)

(or CSI: Sahara)
 
I have a '94 Wrangler Sahara, approx. 125K miles, 4.0 6cyl.
I'm about to make a transcontinental trip and would like to diagnose and fix this problem before I head out.
 
The Jeep starts up fine when cold and runs well on short distance runs. However, once it warms up, it tends to run for about 20 miles before it starts stalling out. Sometimes it does this while driving at speed; other times it does this when I take my foot off the gas preparing to stop.
 
After stalling out, I wait about a minute or two and the Jeep starts right back up again.
 
As I'm in the California desert, I should note that summertime temperatures tend to run in triple digits when the problem seems most prevalent. However, it has happened in the winter especially during wetter weather.
 
Needless to say, I don't want to start cross-country and have the Sahara die out on me. Unfortunately, I'm not mechanically inclined; so, I'd like to have some ideas before a mechanic looks the vehicle over.
 
Also, would I be wise to let a dealer perform the diagnosis -- not usually my first choice since they tend to diagnose problems other than the usual cause -- however, considering my situation, I might go that way.
 
Secondly, can someone tell me what kind of fuse I need for the cigar lighter/radio in the same vehicle? Is the heater on the same fuse? (I would think not, but I'm dumb when it comes to this stuff.)
 
Any suggestions would be helpful.
Thanks!
 
Ciao for now!
Mike

#538 of 1886 97 jeep wrangler auto trans shifting trouble by jen4jr

Oct 09, 2006 (6:56 pm)

My 97 Wrangler has a 3 speed auto trans 59,000 miles. It recently start either not shifting or slipping with a hard shift. When it doesn't shift I can lift my foot off the gas and it will shift fine. It seems to do it more when the vehicle is cold, but doesn't do it all the time. I had the fluid changed after this started and it didn't seem to help.

Even if I was with your Jeep I'd find it very difficult, not to mention time consuming, to find the cause of an intermittent fault that only occurs every twenty miles or so. If you want a WAG, check the fuel tank venting. If blocked, it could be causing enough of a vacuum after twenty miles that the fuel pump can't overcome it. The good news is that it restarts each time so you're unlikely to be stranded.
 
Can't help with the fuse, but it's always worthwhile to have a workshop manual, which is sure to carry that information.
